The Kensington Thunderbolt 3 dock (SD5200DT) has proven it is equally at home plugged into a Windows or Mac device.
2018 is the year of Thunderbolt 3. Almost every new model laptop and tablet has adopted the 40Gb/s, USB-C connection for data and power delivery enabling smaller, thinner devices.
The downside is that almost all expandability requires add-on dongles or docks to get additional HDMI, DisplayPort, USB-A, USB-C, Ethernet, and more.
As GadgetGuy found some docks like the OWC are “Best for Mac” and includes a lot of exclusive Apple features like legacy Firewire 800 and S/PDIF ports.
The Kensington Thunderbolt 3 SD5200DT is “Best for Windows”. It also has a Mac-specific version SD5000T (not tested). I can’t see any external difference, but I suspect it uses more Mac compatible circuitry.
We tested with both a MacBook Pro 13.3 (2017) and a Windows 10, HP EliteBook, x360, 1030 G2 (2017). Mac passed with flying colours. This unit has 85W USB power delivery, so it will handle the MacBook Pro 15” as well.
What we were most impressed with was that the HP saw the device and loaded all the appropriate drivers without missing a beat. The Kensington also met the power requirements of the HP which while only 65W would not work with many other brands of docks.

In the box
- 20V power brick
- .5m USB-C/Thunderbolt cable (note that 40Gb/s can only be achieved at up to this distance without using a more expensive active cable)
- Base documentation
The first impression is that it is solid and well built. While I would have preferred more USB-A ports, the 2.1A port makes up for that as you can safely attach a small passive hub if you need it. Also, many HD and 4K monitors have USB powered ports.
How to connect monitors
USB-C/Thunderbolt 3 standard assumes that all graphics processing is done via the host computer. The limitation on one or two external monitors is determined by the computer’s GPU.
How to connect a single up to 5K monitor
The DisplayPort 1.2 supports sound and video up to 5K over the one cable. You can get DisplayPort to HDMI or VGA/DVI adapters/cables.
